To to whom it may concern.-

Be it known that 1, JAMES C. STALEY, of Glade Mills, in the county of Butler and State of Pennsylvania, haveinvented a new anduseful Earth-Auger; and I do hereby declare the following to be a full, clear, and exact descrip tion thereof.

My invention relates to an improvement in post-hole diggers; and it consists of a pointed IO vertical shaft provided with a handle and cut ting-bit constructed of one piece with four cutting-points, the cuttingedge of which is on four different planes.

In the drawing,A is the vertical shaft, pointed as at B, and provided with a cutter, O, constructed in one piece, having four cuttingpoints, D D D D*, which cutting-points 0perate 011 different planes.

E is a handle secured on the upper end of the shaft A and at right angle thereto.

The operation is as follows: The operator forces the point B into the ground, then rotates the shaft A through the medium of the handle E, the cutting-point D enters the ground, and

following it the cutter l)" enters the ground, and following itthe cutter D enters the ground, and following it the cutter D enters the ground, thereby gradually cutting up the earth, which, at suitable intervals, is withdrawn by withdrawing the digger fronrthe hole formed. The digger is again inserted and the operation repeated until the post-hole is of the desired depth.

Having thus described my improvement, what I claim is- In anearth-auger such as described, the cutting-blades formed from one piece of metal, each blade being inclined at a different angle from the adjoining blades, and the said piece of metal. being provided with a perforation in the center for the reception of a handle, substantially as shown and described.

In testimony whereof I have hereunto set my hand this 23d day of June, A. I). 1885.
